BINNACLE FOR SUBMARINE BOATS,

Application filed August 27, 1904. Serial No. 222,427.

The binnacle as I cles employed onsubmergible and submarine herein shown comprises a casing 7, having aboats built almost wholly of magnetic metal, back and two upright sides,with ties 8 andv 9 such a binnacle having in some instances a across thefront, and in this casing is mounttelltale-compass, a beefing-magnet,other lated a telltale-compass 10.- This is a doubleeralcorrecting-magnets, and means for quadcard transparent compass, and itis pivotally I I5 rantal correction.

it, this bore being in the main large enough (seen best in Fig.2,) andin Fig. i a key is seen I in place on the screw.

The heeling-magnet device M is mounted above the compass where it willbe easy of access in a bracket-arm 8 on the tie 8. In this case (seeFig. 4) the tubular casing 13 is screw-threaded and screws through afixed nut 15 on the arm 8 and is provided with a lock-nut 21. The cap14: on the tubular casing 13 prevents access of moisture to the inclosedmagnets 12.

The heeling-magnet device may be readily adjusted up-or down through thehand-hole in the top of the hood 1.

The quadrantal corrector of the binnacle is best illustrated in Fig. 1.On each side of the casing 7 is secured a threaded rod or screw 22,which projects out at right angles from the casing by preference and isprovided with a nut 23. On the screw is slipped a ball 24, of iron,which has a bore extending through to slip freely over the screw, buthaving a short contracted portion of its length screwthreaded, as seenat 25 at the right in Fig. 1, where the ball 24: is shown in section toillustrate this feature.

As the screw and ball project considerably from the side of the casing7, room is provided for them by a cup 26, screwed into the side of thehood. This cup, which forms in substance a part of the hood, isremovable and affords access to the ball for adjustment along the screw.

It will be noted that all of the magnets are superposed or above thecompass, so as to be readily and conveniently reached for adjustment,although the space in and about the binnacle is necessarily contractedby reason of the requirementfor economizing space. The magnets 12 and 12are inclosed, so as to avoid wetting by condensed moisture, and thetubes containing the magnets are readily removable at will. One key 19would of course serve for adjusting the lateral magnets; but it ispreferred to have two, in case one should be lost, misplaced, or broken.

The binnacle described is especially designed for submarine boats; butobviously its use is not necessarily limited to this class of boats.

As the magnets proper, 12 and 12, are carried in tubes, the magnets,together with their inclosing casings or tubes and attached parts, havebeen referred to as magnet devices and designated by theletters M and M.

At the left in Fig. 1 is shown the means for securing the screw 22firmly to the casing 7 in a readily-removable manner.

The screw has on it a polygonal part 27 to receive a wrench and anenlarged screwthreaded extremity 28, which screws into a socket in ametal block or thickening-piece 29 on the sideof the casing. Thisconstruction provides a firm and rigid fastening, and

yet permits of the ready removal of the screw 22. The part 27 may haveany form adapted to receive an instrument for turning the screw.

It will be noted that in the present construction the magnets are notmounted on and carried by the compass, but on the casing 7, the compassbeing free to maintain its horizontal position, while the binnacle,which carries the magnets, may robk with the movements of the vessel.

Having thus claim- 1. A binnacle, having a compass pivotally mountedtherein, magnets mounted on the binnacle above the level of the compass,and means for moving said magnets toward and from the compass.

2. A binnacle, having a compass pivotally mounted therein, uprightcollared screws 16 mounted rotatively in the binnacle-casing,horizontally-disposed magnets M, each provided with a nut which runs onone of said screws so as to be moved up or down by rotation of thescrew, and upright guideways 20, one for each magnet, the ends of themagnets loosely engaging the respective guideways.

3. Abinnacle, provided with a heeling-magnet mounted directly over thecenter of the compass in a rigid bearing, and havingmeans for adjustingit up and down with respect to the compass.

i. A binnacle, having a casing, provided with a fixed nut, a compassmounted in said casing, and a heeling-magnet device mounted in thebinnacle-casing directly over the compass, said heeling-magnet devicecomprising an upright, tubular, screw-threaded casing, magnets therein,and a cap closing the end of said magnet-casing, said magnet-casingscrewing through said fixed nut for adjustment.

5. A binnacle, having a compass pivotally mounted therein,horizontally-disposed magnets mounted on the binnacle above the level ofthe compass, and means for moving said magnets toward and from thecompass, said means and the magnets being mounted in a readily-removablemanner and being accessible from above the binnacle.

6. A binnacle, having a casing and quadrantal correctors at respectiveopposite sides of same, said corrector comprising a screwthreaded rodprojecting out laterally from the casing, a ball which is threaded onsaid rod, and means for securing said ball in place when set on the rod.7

7. A binnacle, having a casing and quadrantal correctors, each of saidcorrectors comprising a screw-threaded rod 22 which projects outlaterally from the side of the casing, a ball 2 1 on said rod, said ballhaving a part only of its bore screw-threaded to engage the thread onthe rod, and a nut 23 on said rod.
